• To evaluate the effect of olaparib on exposure to anastrozole by determination of steady-state exposure to anastrozole in the presence and absence of steady-state exposure to olaparib• To evaluate the effect of anastrozole on exposure to olaparib…
Primary: To evaluate the effect of a dose increase to 40mg tamoxifen QD for 4 weeks in patients with at least one CYP2D6 variant allele and/or the presence of a CYP2D6 inhibitorSecondary:To evaluate the effect of concomitant use of (potential)…
Inhibition of CYP2D6 enzymes by SSRIs may lead to reduced endoxifen plasma concentrations and thereby possibly influence tamoxifen treatment outcome. Paroxetine is a potent CYP2D6 inhibitor and strongly reduces endoxifen plasma concentrations.…
- To examine the effects of cytochrome P450 induction by rifampicin on the metabolism and pharmacokinetics of tamoxifen and its metabolites. Induction of cytochrome P450 enzyme expression (including CYP3A4, CYP2C and CYP2D6) by rifampicin will…
-To optimize DM-BT by addition of multiple breath sampling and improve it for use in clinical practice-To create a population based pharmacokinetic model based on DM-BT predicting endoxifen serum levels-To identify ideal single or two time points…
This trial studies the effects on quality of life and on time to second progression of the sequence endocrine therapy-capecitabine versus the sequence capecitabine-endocrine treatment. It is anticipated that the time on study (which is the time…
To investigate prospectively how the "TAMRO-profile" performs in a pre-operative treatment setting. In addition we can examine whether the profile is specific for tamoxifen or is predictive for endocrine resistance in general. Also the…
Primary study objective:The primary objective of this study is to evaluate the clinical outcome of dual-chamber ICD therapy with minimized ventricular pacing compared with single-chamber device therapy with settings which are common in clinical…
To determine the influence of morning versus evening administration on the pharmacokinetics of tamoxifen and its metabolites. Amendment: To determine the influence of time of administration (morning (8 a.m.), afternoon (1 p.m.) and evening (8 p.m…
To evaluate the effects of COS with tamoxifen or letrozole compared to standard COS, on oocytes retrieved.
To determine the influence of concomitant administration of tamoxifen and probenecid on tamoxifen and endoxifen(-glucuronide) plasma concentrations
The main objective of this study is investigating whether augmented reality can provoke symptoms in patients with contamination-based OCD by evaluating how this AR HMD symptom provocation compares to a traditional symptom provocation.
The main objective of this study is to investigate whether body ownership directly influnces the perception of pain in individuals with BIID. The secondary outcome examines whether or not AR is also an effective tool for ameliorating physical and…
To compare the plasma concentration of edoxaban in women with breast cancer before and during treatment with tamoxifen.
The main objective of this study is to investigate whether perspective (i.e. first person vs. third person) directly influences the interplay between body ownership and pain perception.
Primary objective:1. To compare the change from baseline of the Area under the curve (AUC) of tamoxifen in patients with breast cancer treated with tamoxifen with and without green tea supplements.Secondary objectives:1. To compare the Area under…
Primary objective1. To compare the Area under the curve (AUC) of endoxifen in patients with breast cancer treated with tamoxifen with and without diclofenac.Secondary objectives1. To compare the Area under the Curve (AUC) of tamoxifen and endoxifen-…
The main objective is: To determine the influence of curcumin with or without piperine, in patients with breast cancer, on endoxifen plasma pharmacokinetics (AUC).Secundary objectives are:1. Other pharmacokinetic outcomes (i.e. clearance, minimum…
The primary objective of this study is to determine the proportion of patients that reach an endoxifen level of 16 nmol/L or higher using MIPD. Secondary objectives: 1. To determine the total success rate of the POP-PK model as well as in different…
To test if tamoxifen treatment, compared to placebo, reduces the progression of the disease in 6.5-12 years old ambulant DMD patients by at least 50% (using the MFM D1 subscore as primary clinical endpoint in group A patients).To test if tamoxifen…
